Dead Areas In The Lawn

Question

both bermuda and rye grass grow everywhere else on the lawn but these 3 areas are always dead. I’ve added gypsum, fertilizer and nitrogen, then broadcast seed and it does not sprout. I water extensively as well.

Answer 1

A soil test may help determine if something is lacking (or too much) in the soil. Too much fertilizer can burn the grass. Are these areas in full sun? Most grasses don't do well in shade. Make sure your lawn fertilizer doesn't include an herbicide when you are spreading seed. Also, when you broadcast the seed, are you raking the areas first to remove dead grass? Watering it every day? Fungal diseases such as brown patch disease or anthracnose can cause large areas of dieback.
